Abstract (en)
A water spray member includes : a plate-like water spray part through which a plurality of shower holes penetrate in a thickness direction, wherein given that: when a shower hole forming surface 46 on the water spray direction side of the water spray part is viewed in the thickness direction, with regard to a first rectangle 52 with a minimum area whose four sides circumscribe the shower hole forming surface 46, the respective dimensions of a first longitudinal side and a first lateral side that are adjacent to each other are denoted as a and b, respectively; and on the assumption of a virtual plane that is perpendicular to the thickness direction on the water spray direction side of the water spray part, with regard to a second rectangle 56 whose four sides circumscribe the group of points at which the respective central axis lines of the plurality of shower holes pass through the virtual plane and that has a second longitudinal side and a second lateral side that are respectively parallel to the first longitudinal side and the first lateral side, the respective dimensions of the second longitudinal side and the second lateral side are denoted as c and d, respectively, the water spray part is formed such that the following conditions (1) to (3) are satisfied.
